Applications include both forwa rd and inverse problems as well as forward problems\, for example para meter identification or modeling of structure-property relationships. The talk will give an overview over a variety of solutions that benefi t from the capability of artificial neural networks to approximate and interpolate complex relationships that are represented by a set of sp arse data. The reason behind is that numerical simulations as well as experiments do often not allow to generate enough data such that the d ata set is not sufficient for a deep-learning approach in connection w ith the complexity of the problem at hand. After a short introduction to artificial neural networks along with recommendations for data gene ration and feature engineering\, the talk will cover a range of exampl es from nanoindentation and material parameter identification\, the im provement of characterization techniques by ML correction methods towa rds recent problems in the prediction of structure-property relationsh ips for materials with complex microstructure. All these examples have in common that a successful ML model typically requires a comprehensi ve understanding of existing knowledge\, expertise in translating this knowledge into meaningful input features\, a compact ML architecture\ , and robust validation of the trained model.

There is pressing need to address major challenges related to the bone diseases. The incidence of bone fractur es is increasing globally and bone grafting now stands as the second m ost prevalent tissue transplantation. In addition to increased number of bone fractures/defects\, bone cancer is one of the cancers with the lowest long-term survival rate. Further\, bacterial resistance is a p ersistent global issue driven by the uncontrolled use of antibiotics. It seems that the long feared postantibiotic era is here\, urging new methods to fight infections. Most scaffolds developed for bone regener ation lack anticancer and antibacterial functionality\, highlighting t he urgent need for multifunctional scaffold designs. The possible solu tion is to treat patients with biomimetic scaffolds based on calcium p hosphates multi-substituted with different trace elements to obtain a multifunctional scaffold for bone regeneration with antibacterial and anticancer properties. The impact of the selected trace elements\, dif ferent scaffold compositions\, and designs was evaluated to gain deep insights into physicochemical properties as well as osteogenic potenti al using human stem cells. The effect of trace elements was investigat ed\, and selective anticancer properties were determined when selenium was used as a substitution element. Furthermore\, the antibacterial e ffect against multidrug-resistant bacteria from clinical isolates was investigated for a wide selection of elements\, confirming silver as t he gold standard.

It exploits the dependence of the backscatter electron intensity on crystal orientation and atomic order . For ECCI a crystalline sample is observed with the backscattered ele ctron signal. The basic principle of contrast formation is that electr ons channel into a crystal lattice when the incident beam enters the l attice along the Bragg angle of a set of crystal planes. In this case\ , very few electrons are backscattered and the observed crystal appear s dark. Every defect that disturbs the order of the lattice planes\, i n contrast\, leads to backscattering and is visible in the ECC image a s bright features in a dark grain. Dislocations\, for example\, appear as bright lines\, stacking faults as bright areas with similar contra st features as those known from transmission electron microscopy (TEM) . Important for good imaging is a small beam convergence for good cont rast\, a small spot size for good resolution and a high beam current f or low-noise images. Additionally\, a sample holder with eucentric til t and rotation capabilities allows to tilt the sample into well-contro lled channelling conditions. The technique can be used very similar to TEM\, however with the serious advantage that a bulk sample is observ ed and not a thin foil. This enables observation of much larger sample s\, simplifies sample preparation\, and it facilitates in-situ experim ents like deformation\, heating\, or gas reaction observations. In the presentation the basic principles of the technique are explained and illustrated.

Furthermore\, photonic sin tering studies are introduced\, illustrating fast and energy-efficient densification of functional ceramics. Dislocations generate local str ain fields and space charge regions that modify defect equilibria\, th ereby enabling dislocation-mediated enhancement of electronic and ioni c transport in oxides such as TiO₂ and yttria-stabilized zirconia\, as well as strongly increased photoconductivity in SrTiO₃. Controlle d plastic deformation produces well-defined dislocation arrays\, and t heir mesoscale arrangement governs macroscopic conductivity. With the help of local microelectrode and tracer experiments\, we can quantify dislocation-enhanced charge and mass transport. Building on these insi ghts\, we can demonstrate that dislocation-rich oxides serve as effici ent photocatalysts for reactions such as heterogeneous H₂O₂ synthe sis and that mechanical tailoring of dislocation density opens a desig n space for catalytic and optoelectronic functionality. Finally\, the talk will introduce photonic sintering of ceramics\, where intense blu e/UV illumination\, assisted by temperature-dependent absorption and e missivity\, enables rapid densification of a range of functional ceram ics within seconds. This approach offers new opportunities for fast\, energy-efficient processing of solid electrolytes and dielectric or se miconductor oxides and points toward advanced light-driven sintering i n ceramic device manufacturing.

Their exceptional properties relate to a fully reversible structural phase transition that enforces a highly nonlinea r thermomechanical coupling\, leading to well-known effects like one-w ay shape memory effect\, superelasticity and elastocaloric self-heatin g/cooling. Despite more than three decades of research and modeling ef forts\, this material class is still a non-standard case in material s imulation\, and often only marginally captured in commercial material simulation software. In the talk\, two different modeling approaches i ncluding their application cases are presented\, with a focus on polyc rystalline materials and micro systems: First\, a model that bases on thermally activated kinetics is developed and applied to dynamic loadi ng cases. Here\, examples for passive and active damping and vibration control of Ti-Ni(-Fe) micro thin film bridges are given. Second\, for capturing large deformation and nonlinear effects for systems compose d of slender SMA beams a model in analogy to J2-plasticity is designed . This is applied to a micro-origami meta-material that is capable of shape changes driven by Joule-heated SMA bending actuators. Furthermor e\, application of this simulation approach to design SMA-based restor ations in dental prosthetics and implants is shown. As a an outlook\, we show how new classes of SMAs\, new production processes and related certification of product life necessitate extensive quantitative simu lations\, based on models automatically adapted to experimental data.

Templated grain growth (TGG) is a clever method for i mparting crystallographic texture in polycrystalline ceramics\, but si multaneous densification and grain growth in inherently heterogeneous (and often bimodal) microstructures make reliably achieving full densi fication difficult. As part of an effort to effectively simulate this TGG process across multiple length scales\, aerosol deposition (AD) is used to create dense\, fine-grain matrices into which single-crystal templates can be ripened. Grain growth studies on these and complement ary sample sets via traditional compaction and tape-cast TGG with seed platelets provide key input parameters for simulations as well as par allel model validation. A low cost optical furnace for rapid densifica tion has also been developed\; using simple broadband blackbody radiat ion\, BaTiO3\, PMN-PT can be sintered\, and many other samples in seco nds.

Although a lot of useful information can be obtained from ex situ imaging\, many materials hav e a different (surface) structure at elevated temperature as opposed t o room temperature\, and in vacuum as opposed to gaseous environment. The specific gas present can even influence the structure of a materia l. This means that traditional TEM images are mostly obtained of mater ials that are NOT in the state in which they are used in practice. One important area of application is catalysis research. The development of differentially pumped ETEM was a significant step in the direction of real in situ TEM\, allowing gas pressures of up to 50 mbar and heat ing up to about 1000 °C. We have developed a micro-electro-mechanical system (MEMS) nanoreactor to bridge the pressure gap. It confines a t hin layer of gas (several microns) in a windowed cell\, thus retaining atomic resolution at pressures exceeding 1 bar by limiting the path l ength of gas the electron have to traverse. The catalyst under study ( or its precursor) can be loaded into the nanoractor prior to the exper iments. Small electron-transparent windows provide both good transmiss ion of the electron beam and stability against the pressure difference . Heating is possible up to about 1000 °C. New developments include i ncorporation of a light source to study photocatalytic reactions.
